There is a stand-alone version, indeed, at
https://svn.r-project.org/R-packages/branches/stand-alone-REngine

It needed a few small adjustments to match current R version, but it  
should be ok now. Don't forget to use R CMD when running your program,  
though, so the demo in the above should work with

make
R CMD ./test

The default setup is now OS X but there are instructions in the  
Makefile on how to use it on other unices and I have tested it  
successfully with Linux and libFoundation.

Cheers,
Simon
